“Both diclofenac and cyproheptadine at 500 µM caused a significant inhibition of DMXAA metabolism in rat liver microsomes.”
“Conclusion: These studies showed that coadministration of L-thalidomide did not alter the plasma DMXAA AUC in rats, in contrast to previous studies in mice, whereas diclofenac and cyproheptadine significantly reduced the plasma clearance of DMXAA in rats in a similar manner to their effect in mice.”
“In contrast, when combined with diclofenac or cyproheptadine , the plasma AUC of DMXAA was significantly (P<0.05) increased by 48% and 88% and the T1/2 by 36% and 107%, respectively, compared to controls.”
“Purpose: Coadministration of thalidomide, cyproheptadine or diclofenac has been shown to increase the area under the plasma concentration-time curve (AUC) of the novel antitumour agent 5,6-dimethylxanthenone-4-acetic acid (DMXAA) in mice.”
